, 14 Claims.

This invention relates to olivaging machines and more particularly tomachines for the rounding of corners of the recesses or passages inbearing jewels, although not so limited.

One object of the invention is a semi-automatic machine whereby therelative movement of the several parts is automatically effected whilthe operations on the passages in the bearing jewels is controlledmanually.

another object of the invention is an olivag ing machine of thecharacter described which is' readily manipulatable to eifect thepurpose at hand.

Yet another object of the invention is the provision of an olivagingmachine whereby a plurality o'f jewels maybe worked upon at one and thesame time.

' A further object of the invention is improved means for positioningthe jewels to be worked upon.

Yet another object of the invention is means to retain the jewels inposition while at the same time capable of simultaneous release for anyacce'ss to the jewels.

Still another object of the invention is to ro tate the jewels whilethey are being worked upon.

It is also sought by this invention to provide an olivaging machinewhich is practical from the standpoint of simplicity of construction andease and convenience in manipulation.

These and other objects of the invention and the means for theirattainment will be more apparent from the following detailed descriptiontaken in connection with the accompanying drawings illustrating oneembodiment by which the invention may be realized and in which:

Figure l is a plan view-of the machine of this invention;

Figure 2 is a view partly in elevation and partly in section taken inthe plane indicated by the line 2--2 of Figure 1 and looking in thedirection of,thearrows-;

Figure 3 is a sectional view taken at right angles to the sectionillustrated in Figure 2 on the line 3-3 of Figure 1;

, Figure 4 is a fragmentary view on an enlarged scale showing jewelsretained in slots by means of positioning or retaining fingers;

, Figure 5 is a planview taken in the plane indicated by the line 5-5 ofFigure 4 and looking'in the direction of the arrows; and

Figure 6 is a view similar to Figure 5 but showing the displacement ofthe jewels in the performance-of work thereon.

Referring first to Figures 1 and 2, the base of the machine is indicatedat II]. This base may be circular in plan and adapted to stand upon atable or other support. It is formed axially with a recess l2 in itslowermost portion which opens into a fru'sto-conical bearing surface Madapted to receive a -frusto-conical annulus I6 by which a table I8 ismounted for rotation on the base Ill. The table is secured to the annu-'lus l-G, as by pins 20 and ascrew 22.

The table l8 is illustrated a rectangular in cross-section andconveniently of a length greator than the diameter of the base. It isformed with a dovetail 2-4 (Figure 3) on its upper surface in which arectangular groove 26 is formed. In the groove 26 is a gib 2B. A pair ofbrackets 30 are mounted on the dovetail 24 so they may be equally spacedfrom the axis of turning 'of the table I8 and to which they are securedin predetermined spaced relation as by the screws 32 countersunk in thegib 28. These brackets support the wire 34 which passes through theaperture 3'6 in the bearing jewels 38, as illustrated in Figures 4, 5and 6.

The upper ends of the brackets 30 are formed with diametricallypositioned grooves 40 adapted to receive a rod 42 retained in positionin the groove by clamp members 43. Spaced arms 44 depend from the rod42, to which the arms are pinned, as at 46, to maintain a rigidrelationship between the arms and the rod. These arms 44 dependdownwardly and the free ends thereof are formed with grooves or slots 48at their lower ends through which the ends of a wire 34 pass and whichends are secured to the arms as by the screws 50.

On opposite sides of the table l8 are diametrically disposed columns orposts 52 (Figure 3 which are secured to the base ID as by the bolts 54.On these columns is mounted a bridge member 56 extending generallytransversely of the table I8 and immediately thereabove. This bridgemember 56 is formed on its upper surface with a dovetail 58 guiding aslide 60. The slide 60 carries, longitudinally, a spacer 62 which issecured to the slide 60 as by the screws 64. Supported on the spacer 62is a bead carrying member 66 shown as an elongated rectangular plate 66formed with a plurality of longitudinal parallel grooves 68 receiving,respectively, the beads 10 (see Figure 4). The bead carrier 66 is shownas positioned on the slide 60 by means of pins 12 passing throughnotches 14 in the ends of the bead carrier 66 and seated in the slide60. To the rear of the slide 60 there is mounted a fixture 16 formedwith ears '8 to which a pitman 80 is pivotally mounted whereby the slidemay be reciprocated.

The beads are rotated by relative movement between the bead carrier 66,actuated by the pitman 80, and fingers overlying and frictionallyengaging the beads, the wire 34 being within the aperture in the jeweland in contact with corners or edges in the apertures. While the jewelcarrier 66 is moved in one direction by the pitman 80, the reciprocatingfingers 86 above the slide mounted, as at 81, on a bridge member which,for convenience, is illustrated as a composite member shown at the rightin Figure 3, as well as in Figure 2. mounted, as at 81, on the bridgemember and the bridge member and fingers are always moving in theopposite direction to that of the jewel carrier 66. This bridge memberis illustrated as comprising a transversely extending block 8| fromwhich rigid arms 82 extend in a horizontal plane on opposite sides ofthe spacer 62 and slide on the slide 60. These serve to guide the bridgein its reciprocation. Extending upwardly from the bridge block BI is anear carrying portion 83 to the ears 84 of which are pivotally mounted aplurality of the so-called fingers 86 extending over the grooves in thebear carrier and overlying the beads in frictional contact therewith.The bridge is also provided with a rearwardly extending portion 88formed with an ear 90 to which is connected a pitman 92. The two pitmen80 and 92 are respectively connected to the ends of a rocking lever 94pivoted as at 96 and actuated by a link 98 connected for reciprocationto some prime mover such as the disk Hi6 driven by the belt I62.

Extending upwardly from the bridge is a pedestal I04 carrying cam meansI06 which will raise the fingers 86 up oiT the beads to permit theirinsertion and removal as will be understood. As illustrated, the cammember I06 is pivoted as at ID! on an ear I08 on the pedestal I04 and isof a length such that when swung downwardly, as by handle Ill], willdepress the inner ends of the fingers, that is, the ends to the right ofthe pivot 87, as viewed, and retain the fingers 86 in an upwardly tiltedposition ofi the beads so that access may be had thereto for removal andreplacement,

It will thus be seen that once the wire 34 has been threaded through thepassages in the jewels 16 and they are disposed in the grooves 68, thatthe jewels will be caused to rotate about the wire by the relativereciprocation of the carriers and fingers. By turning the table H3 at anangle to the slide 60, the beads are moved to positions in echelon withrespect to one another, as shown in Figure 6, whereby the wire isbrought into contact with those edges of the passages which it isdesired to round off, to the desired degree depending upon the angularmovement of the table l8. Since the table is capable of movement withrespect to the slide through a wide angle closely approaching half thecircumference, any desired radius of curvature of the edges, within widelimits, may be effected and it may be said that universal movement ofthe wire with respect to the beads, or vice versa, is permitted by thefact that the beads are free to move in the groove, both longitudinallyof the groove and rotatively with respect thereto with the wire at anypermissive angular relation to the axis of the groove as well as to theaxis of the jewels.

The fingers 86 are pivotally.

skilled in the art in the composition, configuration and disposition ofthe component elements going to make up the invention as a whole as wellas the instrumentalities effecting relative movement of the severalparts, some of which may be united in a single member for convenience inmanufacture and assembly, and no limitation is intended by thephraseology of the foregoing description or illustrations in theaccompanying drawings except as indicated in the appended claims.
